In the above scenario, students are different, but their costumes are the same. We can correlate this scenario to the concept of Like fraction.
 
In a fraction, if the numerator is different but the denominator is same that is known as, Like fraction.
A like fractions are fractions, with the same denominators and different numerators.
Example:
18,28,38
 
Here the denominator of all the fractions are the same, so it is a Like fraction.
